The Fun Never Ends With My 388 Misadventures

Reel deep thoughts...
Can I delete this thread?
I don’t think you have control to do that, but you can always ask a forum moderator to delete it. Anybody know for sure?

I’m kind of hoping not, because there’s valuable information in here about how to prepare before taking things apart with units like the 388, and some steps to take if you don’t prepare…how to logistically dig out. Also, my opinion, but I think it might be worthwhile for others to have some sense of what they might be getting into if they decide to assist you.

Just wanted to say you’re an absolute saint for hanging in this long!

It's not the connections. I hooked the rest up as best I could using wire length and logic and it's still exhibiting the same behaviour. Unless the switching logic is on one of the connectors we didn't get to it can't be any of them.

I think the m,buss board is to blame somehow, but the only possible cause are a couple of possibly cold solder spots on the plus and minus 15v tracks at the connection to the A buss board, and I can't see what those have to do with where a signal is bussed.

Yes, we call them boards over here. It's less syllables than PCB, We're lazy.

I realise no one cares any more, but here's where I am so far.

The stereo buss is fine. The L/R buss is unresponsive.

The sockets for the LED are two conductor Molex connectors which I am not sure you can still get them. I bough a bunch for the card edges of 38 and so on as when the hook breaks the cards will not plug in correctly. That is usually done by amateurs jamming the cards in any old way. Bulls in a China Shop.
